The Titanic's last lunch menu, saved by a passenger, Abraham Lincoln Salomon, who climbed aboard the so-called "Money Boat" before the ocean liner went down, is going to auction, where it is estimated to bring $50,000 to $70,000, the Associated Press reports.

The online New York auctioneer Lion Heart Autographs is offering the menu and two other previously unknown artifacts from Lifeboat 1 on Sept. 30. The auction marks the 30th anniversary of the wreckage's discovery at the bottom of the Atlantic Ocean.

Salomon also took away a printed ticket from the Titanic's opulent Turkish baths, which recorded a person's weight when seated in a specially designed upholstered lounge chair. It bears the names of three of the five other first-class passengers with him on Lifeboat 1. One of four weighing-chair tickets known to exist, it's estimated it will bring $7,500 to $10,000.

The third artifact is a letter written by Mabel Francatelli to Salomon on New York's Plaza Hotel stationery six months after the disaster. She had climbed into the No. 1 lifeboat with her employer, aristocratic fashion designer Lucy Duff-Gordon and her Scottish husband Lord Cosmo Duff-Gordon, who allegedly bribed the crew to row them to safety in the boat that had a capacity of 40.
